the June 14 Episode 10, "Mother's Mercy" -- which killed off a ton of people and blinded one of our badass BFFs -- had 8.11 million viewers. That makes it the most-watched GOT episode to date. And that was even opposite the NBA Finals Game 5!

The Season 5 premiere held the record before this with just barely 8 million viewers. Episode 1, "The Wars to Come," also had a series high 4.2 rating, which is still slightly above "Mother's Mercy's" 4.1 rating. But who really cares about that, since that 18-49 demo is more important to shows that run ads. The bigger number is the overall audience, and with 8.11 million in the U.S., that's the most for HBO's dragon drama so far.
